Dimensions will integrate sounds from your real world environment, blending them into the virtual reality of the game's story and characters in it. Specifically, Robert tells me as an example:
"[Say y]ou are sitting at home having breakfast... You automatically enter the Tranquil Dimension because it is quiet around you. The clinking sounds from your breakfast cutlery spin off into infinity around you and generate melodies in the music... As you finish your breakfast, [game character] Emily from Mission Control appears in your ears, softly telling you that an Artifact has appeared nearby and you could collect it. You take out your device and look on the screen. It shows a map of your real location with the Artifact on your right. You use the beam to collect the Artifact, a special device you gained during Dimensionaut Training."
